I love Agastache 'Black Adder'! I love to see the Butterflies, Bees and/or Hummingbirds on it, getting nectar from it. I have at least three plants in my front yard flowerbed and I am getting two more to plant there.

It is a beautiful and colorful Agastache! Easy to grow if you have excellent drainage and sun. Other than that, it is undemanding and happy.
